Love this, thank you! I also wanted to say...if you like the drizzled icing look, you can also use puffy paint! Its use to make designs on Tshirts or really any kind of cloth like canvas tote bags. In the US we have brands like Scibbles or Tulip Slick. It real name is Dimensional Fabric Paint or Dimensional Paint! I LOVE using the color 'Hot Chocolate' by Scribbles for my fake ice cream sundaes, I use it as the hot fudge or chocolate sauce! Just make sure it says "Shiny" because it give it that 'wet' look too. It dries 'puffy' or dimensional so it doesnt look so flat. I know other people like to mix the gloss Mod Podge & brown paint for their chocolate sauce, but Im not so sure how I like it once it dry. To me it just looks too flat & almost like paint poured onto it. Anyway thanks for sharing your ideas, I love the idea of using modeling paste too! I usually use light weight spackle, but it can get pretty expansive when you use a lot of it!
